Interest rate-sensitive sectors such as consumer staples, discretionaries, real estates trusts, utilities and financials helped push the bourse higher for a second session after NAB economists tipped the Reserve Bank was done tightening monetary policy.
"We're seeing those rate hike expectations move more towards the idea that at the very least the RBA is going to be on hold, and I guess if we continue to see weak numbers on the employment and inflationary fronts, then maybe we'll start to open up to the idea that we have potentially seen the top of the (hiking) cycle," IG market analyst Tony Sycamore told AAP.
Conversely, hotter-than-expected US economic data last week has narrowed bets the US Federal Reserve will have to raise borrowing costs, bolstering the greenback, which dragged on metals prices and hammered ASX-listed miners.
"The damage is being done today by the material sector, and we're now down for a fourth day in a row, and we're about to unwind all of those almost 12 per cent gains, which we saw from the May low," Mr Sycamore said.
